Robust Differential Item Functioning (Robust DIF)

Robust differential item functioning-analyse detekterer items, der opfører sig forskelligt på tværs af demografiske grupper efter at have matchet respondenter på den underliggende egenskab, samtidig med at proceduren beskyttes mod forvrængning fra outliers, model-misfit eller kontaminerede ankeritems. Den anvendes inden for uddannelsestestning, klinisk vurdering og surveyforskning for at sikre, at en skala måler det samme konstrukt lige retfærdigt for alle grupper.
